Valora Augusta Martin (born 1875)

In 1875, in the year that Valora Augusta Martin was born, the Bombay Stock Exchange - the first stock exchange in Asia - was established. It was called "The Native Share & Stock Brokers Association".

In 1891, from March 9th through the 12th, a blizzard hit the south and west of England. Called the Great Blizzard of 1891, it led to snow drifts of up to 15 feet and killed 200 people and 6,000 animals. Fourteen ships sank.

In 1917, Dutch exotic dancer Mata Hari was convicted and executed as a German spy. Since Mata Hari, born Margaretha Geertruida "Margreet" MacLeod, was a citizen of the Netherlands (which remained neutral in World War 1), she could travel freely in Europe. Her travels (and her romantic entanglements) raised suspicion and she was arrested by the French and found guilty. There is still controversy about her guilt although her name has become synonymous with a seductive female spy.

In 1953, on July 27th, the Korean Armistice Agreement was signed. The Armistice was to last until "a final peaceful settlement is achieved". No peaceful settlement has ever been agreed upon.

In 1985, in May, a paper published in Nature by three British scientists reported that a huge hole was discovered in the ozone layer over the Antarctic. It was much larger than expected and is due to the use of manmade chemicals.
